Specific Heat Capacity of ball bearings
Zaid Al-Radaideh
Aim
The aim of this experiment is to measure the Specific Heat Capacity of ball bearings and to state what material is the ball bearings made of.
Hypothesis
We can predict and assume that the Specific Heat Capacity of ball bearings is high such an assumption was made because it is known that metals have a high Specific Heat Capacity, because the balls are made from a metal we can assume that the Specific Heat Capacity is high. The color of the metal and the density of the metal balls bearing give the impression that it is made from copper.
Apparatus
- Ball bearings
- Thermometer
- Water
- Beaker
- Calorimeter
- Bunsen burner
- Platform balance
- hot plate
Procedure
- Measure the temperature of the water using a laboratory thermometer at room temperature, and record the temperature.
- Measure the mass of ball bearings and calorimeter and record.
- Connect the balls using a string so as to make them move using the string so there will be no need in touching them.
- Add water into the calorimeter at room temperature.
- Add sufficient water into a beaker and place the ball bearings in it and then boil the water to 98°C.
- Leave the ball bearings for about approximately two to three minutes.
- Using the string remove the ball bearings quickly from the boiling water to the calorimeter.
- Measure the new temperature in the calorimeter.
